Versuchsvorschrift

3 g of 1-[4-(5-cyanoindol-3-yl)butyl]-4-(2-carbamoyl-benzofuran-5-yl)-piperazine is dissolved in 100 ml of tetrahydrofuran and 10 ml of 2N or concentrated hydrochloric acid. After stirring for 2 to 3 minutes suction filtration of the precipitated crystals is effected. Drying in vacuo at room temperature to constant weight leads to 1-[4-(5-cyanoindol-3-yl)butyl]4-(2-carbamoyl-benzofuran-5-yl)-piperazine dihydrochloride of Form XII which present the characteristic x-ray diffraction spectrum of FIG. 25.
